PROJECT GOALS REMINDER • This project aim at; • Minimize the storage capacity of the mesh potatoes when outputting data information for decision making process • Frequently checking the values and/or mechanisms to compress the data explored before sending it to the database server.
DESIGN OVERVIEW OF THE PROJECT INTEGRATION FRONTEND APPLICATION BACKEND SERVER (MONITORING SYS) ROUTING PROTOCOL (BATMAN-ADV)
DESIGN INTERACTION BETWEEN PCs AND MESH DEVICE (ADVANCED COMMAND LINE) [1] 1. ssh/telnet to the MP PCs 6. PCs, can send and received packet. 5. SECN aggregate this data into one data structure 2. SECN terminal invoke SECN running the configuration setting 3. Query the MP device for its data Routing Protocol e.g. b.a.t.m.a.n-adv 4. MP devices returned its data for viewing
HOW THE B.A.T.M.A.N-ADV ROUTING PROTOCOL WORKS • b.a.t.m.a.n-adv can be use to determine: • The link Quality e.g. batctl o (contains the commands ping, trace route, tcpdump), Node information e.g cat/etc/bat-hosts, • Traffic Performance e.g. athstats, ifconfig
HIGH LEVEL DESIGN DATABASE FOR THE MESH NETWORK9+ The database structure is stored in MeshBoard.sql. The database tables created are “Network” and “Node” [5].
LOGICAL ARCHITECTURE VIEW OF THE DATABASE SETUP FOR THE MONITORING The database design structure uses the view-processor logical architecture [5] Database Server: ‘Network’ ‘Node’ Net-setting Nodes-Infos
LOW LEVEL DESIGN e.g. Configuring Mesh Node Interfaces • The following Steps help to configure each Mesh Nodes: • Use MP Wi-Fi devices like athX and also common ethernet devices, usually ethX. Note X can be 0 and 1 • Mesh Node interfaces added using 'batctlif add ifname', e.g. batctl if add eth0 • batman-adv identify the interfaces it will use to build the mesh network.
LOW LEVEL DESIGN e.g. Classes and communication [4]. • Parameters to tweak when measuring performance of the current network: • ssh into the MP • Move through the batman-adv kernel directory and its subdirectory • ‘cat’ the file to view information e.g hop-penalty setup • ‘vim’ the file to change default values
PLATFORM INDEPENDENT TRAFFIC GENERATORS D-ITG allows generation of network traffic [2]:
